The science behind the Megabomb header may be our greatest engineering accomplishment to date. You can bolt on a Megabomb for as much as a 3hp boost, plus the Megabomb actually reduces noises levels by as much as 1.5dB. Used by Factory Teams, the Megabomb is the next level technology you can have today.
